Genesis? It's always worked great for me, though I'm using the one that comes with 3.9.
Yeah, Genesis has been rock solid always. I've been using it for 10 years on several Amiga setups (030, 060, Peg) with separate version and with OS3.9's version. Never caused any problems. I even had A1200 being web and ftp server 24/7 with it for years.
